I think what is driving the distinction between what the author is claiming and what WashPo is talking about is that whilst it's true the data suggests people gernerally over-estimate their ability relative to others when they under perform, that's not important. It's not important that the average guy thinks he's smarter than 60% of other people. The important bit is that the idiot thinks he's smarter than average.

But I don't think taking a statistical pattern and then applying it to the public persona of a reality TV star is a good idea. If we're going to object to anything, I'll object to that first.
